  1. Re:NSA could break PGP? on PGP Ruled as Relevant For Criminal Case · · Score: 2, Insightful
    The NSA cannot break PGP. Nobody can, not ever.

    Somewhere I hear Vadar saying, "I find your lack of faith disturbing..." ;-)

    PGP uses a passphrase, right? What are the chances this guy's passphrase--now remember he's not only dumb enough to make and locally store child porn, but he doesn't even clear out his browser history--what are the chances his passphrase contains more than, say, 40 bits of entropy?

    You don't have to break RSA or El Gamal or IDEA or Blowfish or whateverTF he was using...just get his keyring and bruteforce the passphrase. Or, if he's just using the symmetric cipher, do the same thing.

    4096-bit RSA over Blowfish is pretty damn strong. Too bad the passphrase is so weak! It's like having that huge shield door from NORAD on your house, except with a full-size doggie door built into the front.

  2. Re:Good. Encryption is a tool too on PGP Ruled as Relevant For Criminal Case · · Score: 4, Insightful
    Just like the presence of a gun during a robbery lifts the crime to armed robbery, the presence of encryption ought to imply not only that the culprit intended to commit the crime but also intended to cover it up as well.

    I see what you're saying...but there are several flaws in this reasoning, both theoretical and practical.

    1. There was no evidence PGP was being used to encrypt anything, or that he was even planning to do that.

    2. The inclusion of PGP in the evidence is intended purely to sway the judge and jurors and presents no real information about the case. This is Cheating. It's like when a newspaper needs a story to be more sensationalistic, they say things like, "Aside from two pounds of marijuana, two guns were recovered from the residence." And then they don't tell you it was just a 22 rifle and a pellet gun.

    3. Everyone has strong crypto on their machine. So by your reasoning, every time a crime involves a computer (which is going to be practically every planned crime these days), it should automatically carry some sort of conspiracy charge. This is pointless, just like saying the presense of envelopes in one's house obviously shows that the owner planned to hide his actions when mailing his co-conspirators.

    4. Telling people that crypto is bad is also Extremely Bad, as attested to by so many other posts today. Crypto is good. Just like we allow a child pornographer to mail his wares undetected in an envelope, we allow him to email them encrypted. The alternative is simply worse, and we choose the lesser of the two evils. Smart people know this; jurors are more easily swayed, as I mentioned in point #2.

    (And for the record, when it comes to child pornographers, there can be no punishment too severe.)

  3. The Explosion Factor on Car Powered by Compressed Air · · Score: 4, Informative

    Someone mentioned the problems of having a (scuba) tank of compressed air sitting in the hot sun...yes, it can be a problem, obviously, if the air heats and expands above the pressure rating of the tank. I am assuming they thought of this and would make the tank adequately strong. (With scuba, the shop fills your tank to the limit, and then the hot sun gives you another 1000 psi and your burst disc goes. This is less than the five-thirds working pressure they push your tank to when they hydro it--I'm sure the tanks on the cars would have some kind of overpressure relief like a burst disc.)

    The French air car article points out, "In the case of an accident with air tank breakage, there would be no explosion or shattering because the tanks are not metallic but made of glass fibre. The tanks would crack longitudinally, and the air would escape, causing a strong buzzing sound with no dangerous factor."

    Well.

    It's great to know that it's a carbon fiber tank so it won't turn into a screaming cloud of schrapnel, but isn't there another issue at work here?

    Now, I don't know exactly where on that tiny car the tank is, but I'd assume it's under the seat someplace.

    The volume of that car is what...two cubic meters? What happens when you instantly put 90 cubic meters of air inside it? (Or under it?)

    Have a look at this rather larger car for an example. Look, ma! No fragmentation thanks to a steel tank, but all that air introduced to an enclosed space jiffy-pops a car like a cheap paper cup.

    I'm more than willing to admit there's more to carbon-fiber tanks than I know. Maybe there's some property that prevents them from releasing all that energy in less than, say, 10 seconds, no matter how badly crushed. But I'm officially skeptical.

    They say there's enough energy in a scuba tank to lift a hook-and-ladder fire truck 20 meters in the air. That's exactly the sort of energy I don't want released near me in a short timeframe. Gasoline is good in comparison because it doesn't tend to do this when the tank is ruptured.

    Then again, a compressed air tank explosion might be just what I need to get ahead in today's Bay Area traffic. Up yours, Fastrak!

  5. Who owns the copyright? on Public Park Designated Copyrighted Space · · Score: 1
    Was the sculpture a "work-for-hire", I wonder? Wouldn't the city then own the copyright? And, if so, wouldn't it count as "public"?

    But let's say that the artist retained copyright himself (herself?). It's my understanding from Bert Krages' book Legal Handbook for Photographers, that images that substantially reproduce the sculpture are derivative works, and therefore are subject to copyright restriction.

    Though not entirely clear, Krages seems to be saying merely taking the picture could be a violation of copyright in these cases.

    However, if you take a picture that doesn't substantially reproduce the work, then you're probably safe. Let's say you take a picture of the reflection of the Bean, but not the edges. The original work is not even shown, so I'm pretty sure that wouldn't count as a violation.

    Also, you could take a picture of the surrounding area where the Bean is only a small part of the picture. This might also be non-infringing.

    Of course, it's all a matter of the always-gray interpretation of Fair Use.

    Also, look at it from the position of the sculpter. You make a sculpture, and then people start taking picture of it and selling them without you seeing a dime. Sounds a little unfair, right? Well, in this case, it goes back to my original question: who owns the copyright on the Bean?

  6. Software can be better than pencil and paper on Open Source Math Software For Education? · · Score: 1
    When it comes to visualizing concepts, a well-placed interactive animation can beat stills-on-paper virtually every time.

    Try to imagine the future of school text books. You think it's going to only be a bunch of static graphs and equations? Not a chance. It'll be "enter some test numbers here" or "slide this bar back and forth and see what happens to this graph."

    And sometimes the hard equation work does get in the way of seeing the concepts, which are no less important. I know a lot of students tend to focus on how to do a math problem instead of what the math problem is, since you get graded on how well you do them!

    Pencil and paper? I'll bet that no matter what software the questioner uses, pencil and paper will also be put to good use crunching equations away just like we all have done. You can rest easy knowing that, I hope. Computers are not a replacement for everything, after all.

    But to say, "Why not use pencil and paper like I did and forget about this software nonsense?" is to ignore an extremely valuable learning tool that has only recently started to be utilized.

    The comments are encouraging for an amateur photographer like me who wants to take good pictures for people to enjoy, and not be eviscerated by a professional critic.

    Definitely room for improvement (sets of sets, printing integration), but they seem to be hard at work making this happen. And it looks like they're going to charge $60/year, which seems kind of pricey compared to the competition.

    What finally (after a couple days) pushed me over the edge to pay them and subscribe were the fact that they have seamless integration with Creative Commons licenses for your photos (cool-factor points), and an open open API for managing your photos through 3rd-party scripts.

    Well, to be fair, they are low quality jpegs, and don't accurately represent what comes from the camera...so the valid question becomes: could you do it over the same pic as a 300dpi print with no jpeg compression artifacts? As a 600dpi print?

    Reading will explain the concepts to you better than screwing around, and careful experimentation (i.e. note taking) will reward you with a FAR better understanding than...screwing around.

    I think we're talking about two different kinds of understanding here, sort of book smarts versus practical smarts. Neither is more important than the other, but I know a lot of people here on slashdot don't like to read manuals, and I was trying to cater to that. :)

    Furthermore, there is so much processing that goes on behind the scenes in digital that you are seldom sure how much of an image is your work, and how much is due to the electronics.

    Shooting in raw mode helps with this. You can process the data however you choose.

    but for really learning photography and composition, they're poor tools.

    Disagree on the composition part. Instant feedback, at least for me, works way better than waiting for the prints to come back. Additionally, I shoot about 100x as many pictures as I ever would if I had to pay to get film processed. Practice, practice!
